Mineral processing | Energy EXchange

Valuable minerals are extracted from rock via the process of comminution (crushing and grinding). This process can be further refined using various means of separation, such as froth flotation, optical sensors and centrifugal devices. The comminution phase can consume more than 50% of the total energy used in a mining.

Mineral processing | metallurgy | Britannica

In primitive times, crushers were small, hand-operated pestles and mortars, and grinding was done by millstones turned by men, horses, or waterpower. Today, these processes are carried out in mechanized crushers and mills. Whereas crushing is done mostly under dry conditions, grinding mills can be operated both dry.

Dry grinding. In the mining industry, dry grinding plants are primarily used when the downstream preparation process requires dry material, or in order to save valuable water resources. Plants from thyssenkrupp Industrial Solutions are in successful operation all around the world, grinding and drying mineral raw materials.

3. Processing of Copper Ore

The process varies slightly depending on the type of ore that is being mined. Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 - 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 - 2 inches. The next step is to feed the crushed ore into a wet.
